error code during intialization
User vcheriya77 (email@example.com) posted:
I get this error often. While trying to intialize around 80 users
around 15 -20 users fail during intialization due to the
following "Failed to create RPC client.RPC-DDE: No response from RPC
server". So i terminate everything start it all over. Now i when do
it again. This error does not occur. But again if i try once again to
intialize to rerun the test again few users fail due the above error.
Why does this error occur on & off and not consistent. Any suggestion
to overcome this is appreciated. Is there any permanent solution.
Re: error code during intialization
This doesn't look like a LoadRunner problem it looks like a problem with your Remote Procedure Call server. How are you ramping up the users, if not slowly I would try doing so.
Sometimes servers cannot cope with the "initial rush" of starting Vusers quickly but once "warmed up" (not very technical I know) they will happly process hudreds of concurrent users. This would manifest itself by your problem usually happening after a period of inactivity on the RPC server.
I have worked on a system in the past where we would get failures for the first 5 minutes when quickly ramping up to 400 - 500 concurrent users, we ignored the 1st 5 minutes for monitoring purposes. As the system wouldn't get this rush of users when live the client was OK with this rather than trying to fix it.
